Join Gabriel Corbett for an in-depth discussion in this video Rigid and flexible assemblies, part of Cert Prep: Certified SOLIDWORKS Professional (2015).
- Whenever you bring subassemblies into a top-level assembly, they are generally in a fixed state. They're not going to be moving around. So if you see here, if I try to drag this part up and down, nothing happens because it's defined by this subassembly here. Now, anything I do to this subassembly, back in the part itself or the assembly itself, is going to be reflected in my assembly over there. So if I move this together a little closer here, and then I go back to my assembly, you can see it rebuilds and it moves because it's based upon a rigid subassembly.
Now, I have the option to switch this to a flexible subassembly, by clicking on it, clicking or right clicking actually and you can click on this one at the far right which is component properties, and then just come down here to solve as flexible. As soon as I do that, now I can move this up and down, and you can see the assembly works as planned. So you might need to, during the exam, switch between flexible and rigid assemblies, especially if you're going to be defining some different dimensions inside of the assembly.
For instance, this one here. If I wanted to find an exact measurement, what I might need to do here is actually go back and change this back to a rigid assembly. And then maybe open this subassembly here, and define a distance in here between these two components. Because I'm looking inside there and sometimes there's a dimension that needs to be placed inside of a subassembly or inside of a component, I can use the section view to look inside there, and now I can add a dimension, for instance mate, between this surface here and maybe this surface here, and give it a dimension of say, in this case here we're in inches, so let's just say it's one inch.
Click ok, but we should be in millimeter-gram-seconds. So if we go and change to that, and then go back and take a look at that distance mate we just created, I can then change it into, let's just type in 30. Click OK. And now that should rebuild when I go back to my assembly here, rebuild, here's the new dimension, and everything else looks OK. So that's working with subassemblies in both a flexible as well as a rigid self state.
Definitely make sure that you brush up on this, and make sure that you know how to switch between the flexible and rigid component states as well as how to add dimensions and have them propagate through to the final assembly.
He also breaks down the three segments of the test (part modeling, configurations, and assemblies), providing strategies that will help you pass each section. At the end of the course, there are two sample exams to practice what you've learned.
- CSWP requirements review
- Working with sketch entities, tools, and relations
- Using the boss and cut features
- Performing sweeps and lofts
- Smoothing corners with Fillet and Chamfer
- Creating linear and circular patterns
- Setting up equations
- Creating multibody parts
- Setting mass properties
- Working with materials and constraints
- Inserting components
- Setting up reference geometry
- Arranging features to change the part
- Working with suppression states
- Using a design table to build configurations
- Establishing standard drawing views
- Annotating your drawings
